Patent JP-S6167750-A (JP)
Title: Production of ferrovanadium alloy
Inventor: SHIROTA YOSHIYASU
IPC: C22C38/00
Filed: 1984-09-12
Abstract: PURPOSE:To produce Fe-V at a high V yield and economy by using V2O2-contg. waste such as smoke ash as a raw material and adjusting the content of Fe and C thereto then adding the raw material to the molten iron in an oxygen top blown converter. CONSTITUTION:V is incorporated in the form of V2O5 together with a large quantity of carbon in the smoke ash emitted from a heat power plant, etc. Such ash is made to make selfcombustion at <=500 deg.C to burn the greater part of the C contained therein and to increase the concn. of the V2O5 contained therein. Iron oxide such as mill scale is added thereto at 0.05-0.15V ratio in terms of Fe2O3 and the content of C is so adjusted as to attain 1-2(V%)+4.0-4.5(Fe2O3). Such material is charged into the molten iron subjected to preliminary refining such as desiliconizing, desulfurizing and dephosphorizing in the oxygen top blown converter. The combustion heat of C by oxygen is used as the heat source to reduce V2O5 and Fe2O3 to V and Fe at a good yield, by which the high-carbon Fe-V contg. 40-50% V is economically produced without using a costly reducing agent such as Al and the electric power by an electric furnace.

IPC: H01L23/31
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To improve the mold releasing property of a semiconductor sealing epoxy resin composition as well as the productivity and reliability by comprising an epoxy resin, phenol resin curing agent, curing accelerator, inorganic filler and a specific alkyl phosphate as essential components to blend alkyl phosphate within a specific range.

Title: Manufacture of semiconductor device
Inventor: SUMA JIRO
IPC: H01L21/02
Filed: 1985-08-28
Abstract: PURPOSE:To allow marking with accurate dimensions without producing dust, damaging the surface of the mask, and forming an irregular, pattern, by forming a partial region which contacts with the circumference of a substrate and is made thinner by more 10mum than that of the other region. CONSTITUTION:A wafer has a structure that the thickness of a region to be numbered is made thinner than that of the other region, and the region to be numbered contacts with the circumference of the wafer. The difference in the thickness of the wafer due to the difference in the regions of the wafer is more than 10mum. When such a wafer is numbered by means of a laser beam, the circumference of the pattern is raised by about 10mum, however, it does not reach the other patterned region of an element, with no damage to the mask. Moreover, if the thick region is surrounded by a thick region, the mask contacts closely with the wafer and cannot be separated when contacting with the mask. However, the mask can be easily removed from the wafer by contacting the thin region with the circumference of the wafer.

Abstract: PROBLEM TO BE SOLVED: To surely absorb urine without leakage by providing a hole for passing the penis on an urine absorptive pad, and folding the urine absorptive pad after passing the penis through the hole to enclose the penis. SOLUTION: A urine absorptive pad 1 has a hole 2. After the penis 4 is passed through it, the urine absorptive pad 1 is folded so as to enclose the penis 4, and laid in using state to absorb the urine in the urine pad 1. According to such the urine absorptive pad 1, since the urine absorptive pad 1 itself is fixed to the penis 4 by passing the penis 4 through the hole 2 of the urine absorptive pad 1, the urine absorptive pad 1 is hardly slipped, and can be quickly replaced by a simple operation of removing a tape to release the urine absorptive pad 1 and pulling out the penis 4 from the hole 2. Further, the proper use for urine and feces can be easily performed, and since the range of moving the body in replacement is minimized, the load to the body can be minimized.
